axis2 就不说太多了，我也不太懂，在apache上自己下载axis的jar包，导入到项目中，

下面就是实现代码了：

import java.util.Iterator;

import javax.xml.namespace.QName;

import org.apache.axiom.om.OMAbstractFactory;

import org.apache.axiom.om.OMElement;

import org.apache.axiom.om.OMFactory;

import org.apache.axiom.om.OMNamespace;

import org.apache.axis2.AxisFault;

import org.apache.axis2.addressing.EndpointReference;

import org.apache.axis2.client.Options;

import org.apache.axis2.client.ServiceClient;

import com.alibaba.fastjson.JSON;

import com.alibaba.fastjson.JSONObject;

public class Demo {

private static void axis2WebService() {

try {

String soapBindingAddress = "http://192.168.0.55:9080/itsm/schemas/ProductServices?wsdl";

ServiceClient sender = new ServiceClient();

EndpointReference endpointReference = new EndpointReference(soapBindingAddress);

Options options = new Options();

options.setTo(endpointReference);

sender.setOptions(options);

OMFactory fac = OMAbstractFactory.getOMFactory();

// 这个和qname差不多，设置命名空间

OMNamespace omNs = fac.createOMNamespace("http://www.chinawiserv.com/onecenter",""); //这个是namespace的str

OMElement data = fac.createOMElement("getProducts", omNs);   //getProducts是方法

// 对应参数的节点

String[] strs = new String[] { "arg0" };

// 参数值 ，以json的格式进行传递

String[] val = new String[] { "{\"userId\":\"1\"}"};

for (int i = 0; i < strs.length; i++) {

QName qname=new QName(strs[i]);

OMElement inner = fac.createOMElement(qname);

inner.setText(val[i]);

data.addChild(inner);

}

System.out.println(data);

// 发送数据，返回结果

OMElement result = sender.sendReceive(data);

System.out.println(result.toString());

//下面是返回的数据解析，返回的是json格式的数据，对string进行jsonobject

Iterator iterator = result.getChildElements();

OMElement result1 = null;

while (iterator.hasNext()) {

result1 = (OMElement) iterator.next();

System.out.println(result1.getText());

}

String re = result1.getText();

JSONObject json_test = JSON.parseObject(re);

System.out.println(json_test.getString("info"));

System.out.println(json_test.getString("result"));

} catch (AxisFault ex) {

ex.printStackTrace();

}

}

public static void main(String[] args) {

axis2WebService();

}

}
